我已经在 Anaconda 上使用以下命令安装了 Cuda
conda install -c anaconda cudatoolkit
之前我也使用以下命令安装 Tensorflow GPU 版本
conda install -c anaconda tensorflow-gpu
但是，Tensorflow-gpu 未激活，当我运行以下脚本时：
from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())
名称：“/device:CPU:0”
设备类型：“CPU”
memory_limit：268435456
地点 { } 化身：12015853371339101357 ]

如果你通过 anaconda 安装 numba，你可以运行 numba -s 来确认你是否有一个正常工作的 CUDA 系统。在带有 CUDA 的 linux 系统上：
$ numba -s
